Patent CA-2452933-A1 (CA)
Inventor: LAMB KARL J
IPC: H02K49/10
Filed: 2002-05-30
Abstract: Dans un coupleur magnétique, une paire de rotors à aimants est montée coulissante sur des tiges. Une matière ferreuse située sur les rotors conducteurs attire les aimants permanents situés dans les rotors à aimants. Dans des conditions statiques ou dans des conditions statiques relatives, la force d'attraction pousse les rotors à aimants vers les rotors conducteurs pour créer un écartement fonctionnel minimum entre ces derniers. Lorsqu'il existe une vitesse de rotation relative significative entre les rotors à aimants et les rotors conducteurs, une force de répulsion pousse les rotors et les éloigne. Au démarrage, des bras de blocage maintiennent les rotors à aimants à distance des rotors conducteurs, avec un écartement plus grand pour un démarrage en douceur. En fonctionnement, la force centrifuge déplace les bras de blocage qui sortent de leur position active. Si la vitesse de rotation de l'arbre de charge diminue rapidement pendant le fonctionnement, les rotors à aimants s'éloignent des rotors conducteurs, avec un écartement encore plus grand, qui les laisse complètement hors de contact mutuel.
